Collection and habitat data.

Mantura chrysanthami was swept or beaten from foliage from a variety of habitats in New Brunswick. These included a barrier beach, a jack pine forest, an old sand dune with red oaks ( Quercus rubra L.), a power-line right-of-way, and a mixed forest. A small series was swept from the foliage of sheep sorrel, Rumex acetosella L. Adults were captured during June, July, and August. Based on personal observations and collecting by the second author in the Ottawa, ON area, Mantura chrysanthemi is monophagous on Rumex acetosella both in the larval and adult stages.

Distribution in Canada and Alaska.

NF, QC, NB ( LeSage 1991; Riley et al. 2003). This is an adventive Palaearctic species now established in most of the northeastern United States ( Riley et al. 2003). Although Mantura floridana Crotch was cited by LeSage (1991) and Riley et al. (2003) from the Maritime provinces, the specimens determined as this species may be Mantura chrysanthemi , and thus the status of the former needs to be clarified.
